I am not sure whether the organizations you mention are the same ones I am referring to. I know that steps have been taken. The question of raising some penalties has been discussed. Personally, I would say that, if you choose to increase penalties, you will also have to look at the situation of the multinationals and limit the attractiveness of tax havens for them as well. They generate greater amounts in taxes.
